On another note, those of you with twins or kids really close in age, how do you handle the toy buying/sharing issue? I've pretty much been buying two of most things that are exactly identical. This cuts down on all of the squabbling over whose toy it is. That said, we still have plently "single" toys in the house that the boys LOVE to fight over and occassionally manage to work out some way of sharing.
What do you do?
